Background:
Heritage animals are traditional breeds that have been bred over a long period of time, adapted to specific environments and requiring less care. The U.S. Postal Service has issued a set of stamps honoring heritage breeds, which include animals such as the mulefoot pig and the Wyandotte chicken. These breeds were established in the Americas, but most of the original populations are now endangered. However, the efforts of farmers and hobbyists have led to a gradual recovery in the populations of these specialized animals. Genetic defects in modern hybrids have also contributed to the revival of traditional breeds. It is hoped that with everyone's efforts, these traditional breeds will be passed on for generations to come.
